る。 2. Description of the Related Art In recent years, much attention has been paid to the photocatalytic action of fine particles of an optical semiconductor represented by titanium dioxide TiO 2 , and particularly to its strong oxidation catalytic action. That is, a particulate matter having a light semiconducting property such as titanium dioxide is converted into light having a band cap energy equal to or more than that (in the case of titanium dioxide,
When irradiated with light having a wavelength of nm or less, that is, ultraviolet rays, electrons in the valence band are photoexcited and move to the conduction band, free electrons are generated in the conduction band, and particles having a positive charge in the valence band. (Hole) is generated. These holes and electrons move inside the semiconductor particles and recombine with time to disappear. However, if air or water, or a compound or ion having a lower vacancy than the holes or electrons exists on the particle surface, those holes and electrons move to the compound or ion through the particle surface, As a result, the holes directly oxidize compounds and ions that come into contact with the particle surface,
Alternatively, a hydroxyl radical, which is one of active oxygen, is generated.

In this way, the photo-semiconductor fine particles form an oxidative active surface when irradiated with light, and act as a catalyst for decomposition of organic compounds, etc. Among the optical semiconductors, titanium dioxide is particularly high in the oxidation catalytic action by such optical semiconductor fine particles, and titanium dioxide is also excellent in stability and safety. Various applications have already been known in which a photocatalyst is formed by supporting it on the surface of a substrate, and its high oxidizing power during irradiation of ultraviolet rays is utilized for decomposing organic compounds and the like.

るものである。For example, hollow glass beads coated with a photocatalyst consisting of a thin film of titanium dioxide are known as a decomposing agent for crude oil that has flowed out to the sea. That is, the crude oil attached to the surface of the glass beads is decomposed by the strong oxidation catalytic action of titanium dioxide activated by ultraviolet rays in sunlight. Recently, its application has been tried for deodorization or deodorization of indoor air, sterilization (antibacterial), and decomposition of stains such as tars and oil slicks of cigarettes, using ultraviolet light contained in natural light or fluorescent light. It activates a photocatalyst and decomposes an odorous compound such as mercaptan or an organic substance such as tobacco tar that is brought into contact by its acid-catalyzed reaction, or kills microorganisms such as bacteria, or suppresses the growth thereof.

The antibacterial deodorant sheet of the present invention is attached to a wall of a kitchen, a bathroom, a washroom, or the like that is irradiated with ultraviolet rays, or furniture to purify the surrounding air and suppress the generation of mold and the like.

しい。The antibacterial deodorant sheet of the present invention comprises a sheet body and an adhesive layer. Titanium dioxide is exposed on the surface of the sheet body. Titanium dioxide acts as a strong oxidation catalyst. For this reason, organic substances in the vicinity of titanium dioxide undergo a strong oxidizing action. In order to withstand the oxidizing action of titanium dioxide, it is desirable that the matrix and binder that holds titanium dioxide to be a binder be a material having high oxidation resistance. From this point of view, as the substance that holds titanium dioxide, synthetic resins such as fluororesins and silicone resins, and inorganic adhesives such as silicates and phosphates are preferable. Therefore, it is preferable that the sheet main body is made of a synthetic resin such as fluororesin or silicon resin mixed with titanium dioxide, or an inorganic adhesive such as silicate or phosphate.

ムを採用できる。Considering that the antibacterial deodorizing function is expected only on the surface of the sheet body, the sheet body is formed of a base sheet and a silicone resin or a fluorine containing titanium dioxide powder laminated on the surface of the base sheet. It is also possible to comprise a resin and a surface layer of an inorganic material. In this case, the strong oxidizing action of titanium dioxide does not act on the base sheet. Therefore, as the base sheet, a normal film known as a normal sheet material such as a polyester film, a vinyl chloride film, or a polyolefin film can be adopted.

きる。The surface layer is made of a synthetic resin such as fluororesin or silicon resin in which titanium dioxide powder is kneaded and can be formed as a thin layer integrally on the surface of the base sheet. Alternatively, titanium dioxide powder may be fixed on the base sheet with an inorganic binder. Titanium dioxide can be formed into a thin film by physical vapor deposition or chemical vapor deposition. In such a case, no binder is needed. However, a base sheet holding a vapor deposited film of titanium dioxide requires high oxidation resistance. In such a case, the sheet body can be obtained by forming the base material sheet with a fluororesin or a silicone resin and forming a vapor deposition film of titanium dioxide on the surface thereof. When particularly strong oxidation resistance is required, an inorganic fiber cloth knitted or woven with inorganic fibers such as glass fibers can be used as the base sheet. A sheet body can be obtained by forming a vapor-deposited film of titanium dioxide or a surface layer of fluororesin or silicon resin in which titanium dioxide powder is kneaded and mixed on this base sheet.

Specifically, the adhesive layer can be formed of an unvulcanized rubber material, thermoplastic elastomer, vinyl acetate resin, or the like. In order to suppress the function of the pressure-sensitive adhesive layer when not in use, it is preferable that a release paper is attached to the pressure-sensitive adhesive layer and the release paper is separated at the time of use to adhere the antibacterial deodorant sheet of the present invention to a predetermined surface.

できる。The smaller the particle size of titanium dioxide, the higher the photocatalytic action due to the "quantum size effect" and the like. Therefore, it is preferable to make titanium dioxide in a colloidal form. Titanium dioxide is preferably formed as a transparent thin film having a thickness of generally 0.3 μm or less, preferably 0.2 μm or less, or as a thin film obtained by laminating such a thin film. It can also be formed by a method such as physical vapor deposition (PVD) or chemical vapor deposition (CVD).

The sun rays also contain ultraviolet rays effective for the antibacterial deodorant sheet of the present invention. Further, a fluorescent lamp such as a germicidal lamp that emits ultraviolet rays also contains ultraviolet rays. In addition, there are some recently developed light emitting diodes that irradiate with ultraviolet rays. For example, a light emitting diode made of a pn-junction gallium nitride (GaN) optical semiconductor crystal emits light (electromagnetic waves) having a wavelength of 360 to 400 nm, that is, ultraviolet rays. Therefore, when there is no other suitable ultraviolet light source, a light emitting diode composed of a pn-junction gallium nitride (GaN) -based optical semiconductor crystal can be used.
